Was not declared in scope

Projects Programming
1

I have just started programming with the Arduino Uno and have had good success using the examples that came with the kit. I am trying to expand on the projects but I am having a trouble with the sketch. I get an Error message"ledPin2 was not declared in this scope" . Can any one point out what I am missing?

int sensorPin1 = 0;
int ledPin1 = 13;
int ledpin2 = 12; 
int sensorValue1 = 0;

void setup()
{

  pinMode(ledPin1, OUTPUT); 
  pinMode(ledPin2, OUTPUT); 
  
  Serial.begin(9600); 
}
void loop()                     
{
 int threshold1 = 150; 
 int threshold2 = 180;
 if(analogRead(sensorPin1) > threshold1){ digitalWrite(ledPin1, HIGH);} 
 else{ digitalWrite(ledPin1, LOW);}
 
 if(analogRead(sensorPin1) > threshold2){ digitalWrite(ledPin2, HIGH);} 
 else{ digitalWrite(ledPin2, LOW);} 
 
 float temperature = getVoltage(sensorPin1);  
 temperature = (temperature - .5) * 100;                                                          
 Serial.println(temperature);                     
 delay(1000); 

 
}
float getVoltage(int pin){
 return (analogRead(pin) * .004882814);                                      
}

Case sensitivity

int ledpin2 = 12;

You probably meant int ledPin2 = 12; as that is what you called it else where in your sketch. C/C++ is case sensitive.

Wow thanks for the help. I must be going bug eyed. I looked at that a 100 times and couldnt see that.

thanks
